ELECTRIC WATER-HEATER Specification of Letters-Patent.

-implication filed May 19, |1915'. Serial No. 29,196.

'0 all whomz't'm'ay concern.'

- Bel it' known that 1,'LOU1s C. HnNiuKsnN,

a citizen of the' United States, residing at Port-land, in the'county ofMultnomah. and

- State ofv Oregon, have invented new and .useful Improvements inElectric lVater- Heaters', of which the-following is a specification. in 'l L This inveiit'ioh relates to hot'water heaters andl `espet'ziallyto -lheaters of the instantaneous. typ'e.v I The main' object of thisinventionv is to provide'a heater which may be connected into" thepiping-'systei'nof a house and which will Abe automatically operated bythe flowl of waterv through the system. .4

` #Another ob'ect is to 4provide a heater having an electricalresistancecoil. inclosed in a -container which is in' communication v.with thehouse system and an electrical contact niaking'ineans foi-closing theelectrical circuit' which will i be ,operatedv by 'the iiow ot .waterso,that,if any valve in the'system is openeclfor the dischargeof water,the heater will'be.thrown-into operation. l

lt is a :further obiect to provide an' electrical heaterlwhich comprisesya 'container embodying theheating element a'nda valve.

.which will close and preventthe circulation of heated water contained4tliereinlack into,

the feeder system when water is not being used in the house system.

The terminal 8 -comprises a threaded stem4 9 adapted 'to re-yceive a thumb nutj10 and a half round head ..11 -provided with a grooveVfor a screw driver. NA,- bushing 12 insulates the terminal ppst 8vfroin'the'tubular member G. An angle member .'13 is disposed upon thepost 8 and Connected-.to the angle member 13 -is one end of a heatingelement which comprises units as illustrated in Fig. (Storming a stai'skeleton expanded presenting a large vsurface to the water which will'passthiough the tube T. A terminal postl is disposed near the flower endof i tubular member G and coi-nprises a threaded stemvhai-'ing a' head.grooved to receive a screw driver. A'ineniber 16 is mounted upon thestem of .the post 15 and between the head of the post and'a bushinglfwhich insulates the post from the tubular membei' (5. y

, The nieniber ,'16 provides onecontact .for'a circuit closing device.lConnected Vto the e Patented Dee. A251915.

"laterally .of the plane of the star, thereby i lower endv ot' heatingelement 1i is an angle memberilo .which is provided with upturnedportions 1l)A and 520i The upturned portion '#20 provides. the point of1connection to the The legs ofthe angle A tube 25* isv secured in thenipple :23 and the lower end thereot` isattached to .the piping for thehouse. A valve 26 which has an .insulated head Q7 and alstem QS isdisposed' within the'tubular member 6' with its stem extending into thetube 25. Disk 21 is secured to insulation :'27 so that 'the disk moves'with stem 2S.' Stem 2S is provided with grooves 20 which have asubstantially right angle shoulder at the upper portion and formsurfaces against which the water impinges` in its-How into the heater. Acap .30 is secured to theupper end of the tubular member 6,' awasher 31being. interposed between the cap and tubular member to pro# lio ride -anon-leak joint. rlhe cap E@ has a threaded nipple 32 into Which pipin tothe hot Water is attachee 85:3 indicates an ordinary faucet, Terminalposts S and are adapted to he connected to any source of electricalenergy.

vReferring particularly to the construction y shown in Fizl with faucet33 closed, no

Water is owing through the system, valve 26 Will loe seated and theelectrical circuit is open by reason of the breakbetween contact points16 and 18. The valve 26 pre? iients Water in the heater from circulatingback into the system, beyond the'heater. Upon opening the faucet 33 thepressure offwater lifts valve 26 and the` inlowing Waterimpingingagainst the shoulders forming recesses 29 and the head 2'? fwill main--tain the Valve in its upward yposition in which 1t. forces disk 21against terminals 16 and 18, thereby closing the electrical circuit. Theflow ofelectricity along the heating element le'causes heating of thesame and the Water flewing through the heater comes into intimatecontact with the several units so that 1t isthoroughly heated. W henfaucet 33 is closed valve 26 drops due to -its to one pole of a sourceof electrical energy, acontact member connected to the other end of saidheating element, a terminalldisposed adjacent saidiirst named contactmember adapted to be connected to said source of electrical energy,areciprocable contact member disposed to close the circuit, and a valveincluding a: sternv With channels thereon ladapted to be acted upon bythe impact of flowing liquid, and disposed to Vactuate said reciprocablecontact member.

-pact surfaces for the Water.

An electrical Water heater, comprising a liquid. container, a heatingelement disposed in said container, means to supply electrical energy'vto said heating element, one terminal thereof connected to said heatingelement, a tubular inlet conduit cornn nected to said container, a stem,a reciprocable dish of electrical conducting material mounted upon vsaidstem and disposed for engagement With ,a terminal of the heating elementand the other terminal of the source of electrical' energy, said stembeing disposed in'said tubular inlet conduit and provided with impactsurfaces for lthe Water.

In Witness that I claim the foregoing I have hereunto subscribed my namethis th day of April, 1915. f p
